Surface underway pCO2 measurements aboard the RRS Discovery during the Atlantic Meridional Transect (AMT21) cruise from 2011-10-03 to 2011-11-09 (NCEI Accession 0170365)
PACKAGE DESCRIPTION: This dataset includes surface underway data collected aboard the RRS Discovery during the Atlantic Meridional Transect (AMT21) cruise from 2011-10-03 to 2011-11-09. These data include partial pressure (or fugacity) of carbon dioxide - atmosphere, partial pressure (or fugacity) of carbon dioxide - water, sea surface salinity, sea surface temperature and barometric pressure. The instruments used to collect these data include carbon dioxide (CO2) gas analyzer, shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement. These data were collected by Vassilis Kitidis of Plymouth Marine Laboratory.
